The only other thing I would add is that at the time those submarines were purchased, which is a considerable period of time ago, there wasn't a lot known as to how much it would cost. At the time the $35 million was put forward, it was based on an absence of information. As well, we were told that they had to build supply chains to be able to have the parts to do the in-depth maintenance that was needed and to develop the procedures.
We understood that it's not entirely apples to apples, but at the same time it's an absence of information to more information.
